To @ZZ whom t may concern:

Be it known that we, DANIEL A. KEATLNG and JAMES TATEM, citizens of theUnited States, residing at Bridgeport and Putnam, respectively, in thecounties of Fairfield and Windham, respectively, and State ofConnecticut, have invented certain new and uscful :improvements inPicker Sticks, of which the following is a specification.

This invention relates to an improved` construction of Vcombination woodand metal picker stick of the type employed to drive the shuttle .acrossa loom; and the object of this invention is to provide a picker stick uof this character having its upper portion of wood and its lower portionof metal in tubular form thereby obtaining the required resiliency ofthe wood and at the same time obtaining the increased strength of themetal for absorbing the hammer-like shocks of the shuttle in receivingand throwing the shuttle across the loom. y y

A furtherobject of this invention is to form the upper end of thetubular metal portion to provide a socket for the reception of the lowerend of the wooden portion, also where the stick is pivotally. mounted topierce the side wallsnear the'lower portion of the tubing forminginwardly-proyecting iianges about the hole to receive the pivot pin onwhich the device may swing.,

lVitlithese and other objects in view, theV invention consists ofcertain novel features of construction, as will bc more fully.described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a side elevation of our improved combination wood and metalpicker stick, showing the lower end of the wooden portion as insertedinto the tubular upper end of the metal portion.

Figure 2 is an edge view of the picker stick.

Figure 3 is an enlargedsection on line 3 3 of Figure 1, showing themetal tubular portion as folded into rectangular shape..

Figure l is a section on line t-t of Figure 1, showing the inturnedstock of the side walls about the pivot pin to form extended bearingstherefor.

1t is found in the practical construction and operation of picker sticksfor looms that, when made entirely of wood their operlating life, owingto the severe hammering treatment to which they are subjected, is veryshort. lt is also found that in securing the strength of an all-metalpicker stick it must also be extremely light andat the same time shouldhave the resiliency or substantial yieldability of the all-wooden pickerstick which is usually formed of hickory.

Therefore, in order to combine these requirements of strength andyieldability. we have formed a picker stick of combined metal and wood,the wood providing the elasticity while the metal provides the necessarystrength about those portions where this greater. strength is required.l.

By this construction, when one portion of the stick is broken and thrownaway the unbroken portion can be remounted in the fresh portion; and thefollowing -is a detailed description of one embodiment of our presentinvention by which these advantageous results may be accomplished:

With reference to the drawings, lO-designates the upper portion of ourimproved construction of picker stick which is formed of wood usuallyhickory. the same being preferably rectangular in cross section largerat its lower end and tapering towards its outer end. This wooden portionis preferably formed of a length substantially one half that of theentire stick but its length may be of any desired proportion thereof.

The lower portion ofv this stick is herein shown as being made intubular form as at 11 and the tube may be made in any'desired manner andof any desired shape in cross section, but we preferably form the sameof sheet metal andfold this metal to form side walls 12 and edge walls13 and 14, rectanguvlar in cross section. The edges of the strip ofmetal are caused to abutat 15 along the length of the tube to form theedge wall 14 thereof. n

The upper end of this tube is shaped to provide a socket for thecorrespondingly 18 and turned thenstock inwardly about the piercing asat 1.7 'forming elongated bearing portions for the reception oit thepivot pin (not shown) on which the picker stick oscillates when or" thetype to loe mounted on a pin for this purpose.

ln some instances, we'also 'torni the side walls l2 a little longer thanthe edge walls 13 and lll thereby providinga groove or recess 19 in theend or' the metal porti-on for the reception of the return strap (notshown).

N ear the upper end oi the metal portion, we have also provided a seriesot holes 2O to which the operating mechanism may be connected.

lVe do not wish to be limited to mounting'our improved picker stick tooscillate upon a pivot pin as other suitable means for supporting thelower end may be employed.

Our improved picker stick is extremely simple and practical inconstruction and eiective in its operation and its working life is muchlonger than that of the allwood picker stick and at the same time willgive the required resiliency which has heretofore been obtained by anall-wooden picker stick.

The foregoing description is directed solely towards the constructionillustrated, Abut we desire it to be understood that we reserve theprivilege or resorting to all the mechanical changes to which the deviceis susceptible, the invention being deiined and limited only by theterms of the appended claims.,

No claim:

l. A picker stick having its upper portion 'of wood and its lowerportion formed of a. single piece oi" metal in tubular -form throughoutits length.

2. picker stick having its upper portion of wood and its lowei` portionof a single piece ot sheet metal folded into tubular form.

A picker stick having its upper portion oil wood and its lower portionof a single piece of sheet metal folded into tubular form angular incross section througlout its length. y

4l. A picker stick having substantially its upper halt ot wood and itslower half of a single piece of sheet metal folded into tubular formangular in` cross section threugl s out its length, its opposite sidewalls being pierced to. receive a pivot pin.

5. A picker stick having its upper porn tion of wood and its lowerportion formed of a single piece ott metal, of tubular form throughoutits length formed to provide a socket at its uppe1 end, for the wood,and spaced apart side walls at its lower end pierced to provide bearingsfor the pivot Pm" 6. A picker stick having its upper portion ol wood andits lower portion of a single piece o'l metal in tubular form,v theupper end of the tube Vbeing 'formed to receive and closely embrace thelower end or' the wood, and its lower end having its opposite wallspierced to receive and provide a bearing for a pivot pin.

A picker stick having its upper portion or wood and its lower portionVot sheet metal folded into tubular Jiform, the upper end or' the tubebeing tormed'to receive and closely embrace'the lower portion of thewood and the walls of its lower portion bepiereed to receive a pivotpin.

8. A picker stick having its upper portion oitl wood and its lowerportion of sheet metal folded into a tube rectangular in cross sectionand formed at its upper end to receive the end of the wood and the Vsidewalls or" its lower portion being pierced to receive the pivot pin.

9. A picker stick having substantially its upper halt ot wood andsubstantially its lower half of sheet metal folded into tubular form,the upper endv oli' the tube being formed to receive the wood and thewallsV adjacent its lower end being `pierced' and the stock turnedinward about the piercing to provide an elongatedl bearing for the pivotpin. l0.
